PLOW.

Application filed December 2, 1919. Serial No. 341,889.

To all whom it may concern:

Be it known that I, JosErH N. PARKER, a citizen of the United States, and a resident of Bedford City, in the county of Bedford and State of Virginia, have invented a new and Improved Plow, of which the following is a full, clear, and exact description.

The object of the invention is to provide a plow with means disposed convenient for the plowman for controlling the traction of the implement; and to provide means manually manipulated for varying in service the operating angle of the furrow turning tool.

In the accompanying drawing forming a part of this specification similar characters of reference indicate corresponding parts in all of the views. v Figure 1 is a side elevation of a mold board plow and the fragment of the plow beam to which the same is attached, the view being taken from the land side and showing a setting lever with which the mold board is provided;

Figure 2 is a similar view, the setting lever being removed; and

Figure 3 is a detail view in perspective on an enlarged scale, showing as a unit the setting lever.

Referring to the drawing, 10 is a portion of a plow beam and 11 a plowshare. The plowshare 11 is pivotally mounted upon the plowbeam 10 by a bolt 12. The plowshare on the land side of the plow has an elongated slot 13 curved concentric with the bolt 12. llhrough the slot 13 extends a bolt 14, said bolt being screw threaded to receive a nut 15 and a rocking lever 16. The lever 16 is pivoted on the bolt 14 and is pivotally connected by a link bar 17 with a pin 18 in the land side 19.

The lever 16 has a vertical extension 16- and a horizontal extension 16*. Both extensions have offset ends 16 disposed in opposite directions to form foot rests for the operation of the lever 16.

IVhen thus provided with the lever 16 and a plowshare pivotally attached to the plowbeam, the angle of operation of the plow, may be quickly altered and that without suspending the plowing operation. If the plowing is beingperformed in hard ground, which resists the sinking of the plow, the operator may by reaching forward with his foot. Dress on the extension 16*,

elevate the toe of the share 11 with the ef-' feet that the burrowing of the plow is thereby modified.

It will thus be seen that at all times the depth of the operation of the plow may be varied and at will, without suspension of the plowing operation.

I claim:

1. In a plow, a beam having a downwardly extending portion, a plowshare pivotally mounted on the lower end of said portion of the beam, and means under the control of the plowman for swinging the plowshare without stopping the plowing operation to cause it to run deeper or shallower.

2. A plow of the walking type, comprising a frame having one of its side bars curved downwardly to form a plow beam, a plow pivoted to the lower end of the beam, an angular lever pivotally mounted on the beam and having each of its memhers provided with a foot rest, and a link connecting the lever with the landside of the plow.

3. In a plow of the walking type, a frame having one side bar curved downwardly to form a plow beam, a plow pivoted to the lower end of the beam and provided with a curved slot on its landside, a bolt secured to the beam and extending through said slot, an angular lever pivoted on said bolt and having a foot rest on each member thereof, and a link pivoted to one member of the link and to the landside.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOSEPH NICHOLAS PARKER.
